The hazard perception test is part 2 of the theory test, taken immediately after the multiple-choice questions. Many candidates underestimate it — but with the right strategy, it's very passable. This guide explains exactly how it works and how to approach each clip.
1What is the hazard perception test?
The hazard perception test consists of 14 video clips filmed from a driver's perspective. In 13 of the clips, there is one 'developing hazard'. In one clip, there are two developing hazards.
This gives a total of 15 hazards to identify across the 14 clips.
A 'developing hazard' is something that is beginning to emerge and will require you to take action — such as a car pulling out, a pedestrian stepping into the road, or a cyclist moving towards your path.
The pass mark for hazard perception is 44 out of 75. Each hazard can score 0–5 points depending on how early you identify it.
2How scoring works
Each developing hazard has a scoring window — a period during which the hazard is beginning to develop. If you click as the hazard begins to emerge (early in the window), you score 5 points. The longer you wait, the fewer points you score. If you wait too long, you score 0.
• Click early in the window = 5 points • Click mid-window = 4 or 3 points • Click late in the window = 2 or 1 points • Click after the window = 0 points
You can click as many times as you want — but if you click in a pattern (rapidly and repeatedly) the test will detect this and score 0 for that clip.
💡 Tips
- •Never click continuously or in a rhythm — it's detected as cheating and you score zero for that clip.
- •You don't need to be first click to score 5 — one well-timed click in the early window is enough.
3What to look for
A developing hazard is not just any potential risk — it's something actively emerging that will require you to brake, steer or change speed. Look for:
• Vehicles pulling out from junctions, driveways or parking spaces. • Pedestrians about to step into the road — especially children, elderly, or near parked cars. • Cyclists moving into your path. • Vehicles slowing unexpectedly ahead. • Animals near or on the road. • Vehicles overtaking towards you. • Road conditions changing (wet, narrow, junctions ahead).
Some things look like hazards but don't score — stationary cars, distant pedestrians on pavements, and road signs alone don't count.
💡 Tips
- •Ask yourself: 'Would I need to slow down or change direction because of this?' If yes, click.
- •Watch for clues — a parked car with brake lights on, a pedestrian looking across the road, a car nosing out.
4Strategy and practice
1. Take the test seriously from the start — even the first clip has a hazard. 2. Keep your eyes moving — scan the whole scene, not just the centre. 3. Click once when you spot a developing hazard forming — then wait to see if there are more. 4. Stay calm — if you miss a hazard, forget it and focus on the next clip. 5. Practice daily using the DVSA hazard perception practice tool or a reputable app.
The most common reason for failing hazard perception is clicking too late — waiting until the hazard is obvious rather than identifying it as it develops.
💡 Tips
- •The DMJ Theory Test Quiz (/theory-test-practice) is great for multiple-choice, but also use the DVSA's official hazard perception practice clips.
- •Try to watch driving YouTube videos and identify developing hazards as they happen — it builds the skill naturally.
5Common mistakes
• Clicking too late — the hazard is fully developed before you respond. • Clicking randomly throughout the clip — triggers the cheat detection, scoring 0. • Focusing too much on the centre of the screen — use peripheral vision. • Not practising enough — hazard perception is a skill, not knowledge; it requires repetition. • Forgetting that one clip has two hazards — many people only find one.
💡 Tips
- •Always keep in mind: one of the 14 clips has TWO developing hazards. Don't relax after clicking one.
